Abstract
An apparatus and method for measurement of liquid flow through use of a volumetric mass balance.
Claims29
A liquid flow meter, comprising:
- an enclosure;
- a volumetric measuring container located in said enclosure, said volumetric measuring container having a selected liquid volume capacity;
- said volumetric measuring container pivotally mounted to said enclosure about an axis of rotation;
- said volumetric measuring container having a counterbalance weight;
- said counterbalance weight maintaining said volumetric measuring container in a static filling rotational position until filled to said selected volume capacity;
- said enclosure having an influent port for directing liquid flow into said volumetric measuring container;
- said enclosure having an effluent port for discharge of liquid from said volumetric measuring container;
- and
- a counter providing an indication of total flow volume through said enclosure.

A method for measuring liquid flow, said method comprising steps of:
- (a) providing an enclosure containing a volumetric measuring container having a selected liquid volume capacity, said volumetric measuring container being mounted upon a rotatable pivot having an axis of rotation and normally maintained in a static filling position;
- (b) flowing liquid into said volumetric measuring container;
- (c) filling said volumetric measuring container by flow of said liquid through an influent port in said enclosure until said volumetric measuring container reaches said selected volume thereby rotating said volumetric measuring container about said axis of rotation;
- (d) discharging said liquid contained within said volumetric measuring container;
- (e) channeling said liquid into an effluent port;
- and
- (h) increasing a counter to indicate running total of said discharges.

A liquid flow meter, comprising:
- an enclosure;
- a volumetric measuring container located in said enclosure, said volumetric measuring container having a selected liquid volume capacity;
- said enclosure having an influent port for directing liquid flow into said volumetric measuring container;
- said volumetric measuring container adapted to discharge when filled to said selected volume capacity;
- said enclosure having an effluent port for directing liquid flow out of said enclosure;
- a counter providing an indication of discharge cycles, said counter positioned in a location sealed from an interior cavity of said enclosure;
- and
- wherein said counter is activated during discharge of said volumetric measuring container.
